Kalsi Engineering has been conducting 10,000 psi tests directed at increasing the pressure capacity of hydraulic swivels, washpipe assemblies, and similar applications. Our previously reported 320-hour and 368 hour tests […]
Rotary Seal Blog
Blogging is a way for Kalsi Engineering to provide up to date information more quickly than we can through traditional information channels like our seal handbook and static web pages. Here you will learn how we are working to solve industry problems through posts about new rotary seal products and posts about testing directed at specific industry problems and applications. You will also learn about the people who make it all happen, as we highlight the achievements and milestones in their lives. Visit our blog for the latest information on Kalsi-brand rotary seals and other Kalsi Engineering products and services.
Video of a 368-hour, 10,000 psi washpipe test
Plastic Lined Kalsi Seals™ have the most pressure capacity of any polymeric rotary shaft seal. This video explains why. We are pleased to announce a new video (above) […]
Testing Hybrid mud motor seals with increased compression
In late 2019 we blogged about concentric and eccentric testing of Kalsi-brand rotary seals with dynamic lips that were significantly wider than those of our 507-series Wide Footprint Seals™. The […]
Kalsi Engineering COVID-19 safety measures
As a critical provider of products and engineering services to nuclear power plants and the oil and gas industry, Kalsi Engineering has taken various steps to promote safety and preserve […]
A new video about high-pressure oil seal testing
Our new generation of high pressure rotary shaft seals is redefining the pressure capacity of high pressure rotating equipment. This video explains how we did it. Here is a new […]
Testing Super Wide Seals™ for drilling fluid-to-oil partitioning service
Many rotary seals that partition drilling fluid from lubricant are used with lubricant overpressure, which improves the ability of the seal to exclude abrasives. With partitioning seals, the typically recommended […]

Kalsi Engineering employee Lannie Dietle is the 2020 recipient of Epsilon Pi Tau’s Region 1 Warner Professional Practice Award for exemplary achievement as a practitioner in a technology profession. A […]
400 psi reverse pressure testing with runout
In a previous blog, we reported on successful 162°F (72.2°C) tests of the tanged 3.00” (76.2mm) PN 701-10-11 rotary shaft seals with 0.010” (0.25m) intentional runout. In one test, the […]
A 100-rpm test of a 10.49-inch RCD seal at 1,500 psi
We are pleased to announce a successful 200-hour-plus test of a 10.49-inch (266.45mm) BDRP Seal™ at 100 rpm and 1,500 psi differential pressure. The used test seal is still in […]
Two 1,500-psi tests of 10.49-inch BDRP Seals™ at 75 rpm
BDRP Seals (Figure 1) are Plastic Lined rotary seals that were developed to provide hydrodynamic interfacial lubrication in either direction of differential pressure and either direction of rotation. This design […]
